## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability northline-sun-events-sample-3593e495 -d '<json body>'
```

Example prompt: What time is sunrise, sunset, and solar noon at latitude 37.7749, longitude -122.4194 on June 21st?

## When to prefer this

Choose this endpoint when you need precise, astronomically computed sun event times (sunrise, sunset, twilight phases) for a specific geographic coordinate and date, especially in a pay-per-call context with no API key setup required. It is well-suited for agents needing occasional one-off lookups without account registration. The sample endpoint is ideal for testing or low-volume use cases.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Missing required date or coordinate parameters returns a 400-style error
- Payment not supplied or insufficient USDC triggers x402 payment required response
- Extreme polar coordinates with no sunrise/sunset (polar day/night) may return null times or special values
